There's a fantastic passage in Romans 8, starting at verse 31:
31 What, then, shall we say in response to these things? If God is for us, who can be against us? 32 He who did not spare his own Son, but gave him up for us all—how will he not also, along with him, graciously give us all things? 33 Who will bring any charge against those whom God has chosen? It is God who justifies. 34 Who then is the one who condemns? No one. Christ Jesus who died—more than that, who was raised to life—is at the right hand of God and is also interceding for us. 35 Who shall separate us from the love of Christ? Shall trouble or hardship or persecution or famine or nakedness or danger or sword? 36 As it is written:
“For your sake we face death all day long;
we are considered as sheep to be slaughtered.”
37 No, in all these things we are more than conquerors through him who loved us. 38 For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, 39 neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
(From the NIV)
I love verse 31, especially where it says "...If God is for us, who can be against us?". Have you ever considered how amazing this passage of scripture is?
Matthew 28 v 18-20 answer the question:
17 When they saw him, they worshiped him; but some doubted. 18 Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
(From the NIV)
"All authority in heaven and earth" means that nobody or nothing can stand against us.
God is on our side and He wants us to succeed. He wants us to live lives that are full of Him and He is interested in all that we do.
In fact, He is so interested in us that He talks about us all the time. Jesus is interceding for us, bringing God's will into being in each of us.
When you pray, pray with authority. Nothing can stand against us, we are in a position of victory, one that has been around since Jesus said "It is finished" on the cross.
That means He defeated Satan, sin, sickness, pain, suffering, sadness, death and everything else that is anti-God.
